The analysis of historical musical instruments is becoming more relevant and the interest is increasingly moving toward the non-invasive reflection FTIR spectroscopy, especially for the analysis of varnishes. In this work, a specific infrared reflectance spectral library of organic compounds was created with the aim of identifying musical instrument materials in a totally non-invasive way. The analyses were carried out on pure organic compounds, as bulk samples and laboratory wooden models, to evaluate the diagnostic reflection mid-infrared (MIR) bands of proteins, polysaccharides, lipids, and resins by comparing reflection spectra before and after the KK correction. This methodological approach was applied to real case studies represented by four Stradivari violins and a Neapolitan mandolin.
对历史乐器的分析正变得越来越重要，人们的兴趣也越来越转向非侵入式反射傅里叶变换红外光谱法，尤其是用于清漆分析。在这项工作中，创建了一个特定的有机化合物红外反射光谱库，旨在以完全非侵入的方式识别乐器材料。对纯有机化合物、块状样品和实验室木制模型进行了分析，通过比较柯克（KK）校正前后的反射光谱，评估蛋白质、多糖、脂质和树脂的诊断性反射中红外（MIR）波段。这种方法应用于以四把斯特拉迪瓦里小提琴和一把那不勒斯曼陀林为代表的实际案例研究。
